Upgrading to a New Cisco IOS Release

Saving Configuration Changes

Enter the copy running-config startup-config command to save your configuration changes to
nonvolatile random-access memory (NVRAM) so that they are not lost if there is a system reload or
power outage. For example:
Router# copy running-config startup-config
Building configuration...
It might take a minute or two to save the configuration to NVRAM. After the configuration has been
saved, the following appears:
[OK]
Router#
You can use the question mark (?) and arrow keys to help you enter commands.
Timesaver
Each command mode restricts you to a set of commands. If you are having difficulty entering a
Timesaver
command, check the prompt and then enter the question mark (?) for a list of available commands. You
might be in the wrong command mode or using the wrong syntax.
Timesaver If you want to disable a feature, enter the keyword no before the command; for example, no ip routing.
You need to save your configuration changes to NVRAM so that they are not lost if there is a system

reload or power outage.

Step 1 Display the contents of Flash memory:
Router# cd flash:
Router# dir
Directory of flash:/

32768000 bytes total (13041600 bytes free)
Step 2 Copy the new image from the remote TFTP server into Flash memory. Make sure that you specify your
own TFTP server's IP address and Cisco IOS filename. If you encounter issues with upgrading the
image, be sure that you can ping the TFTP server and that appropriate directory permissions are
configured on the TFTP server. To see the bangs (!) during the download operation, enable line wrap in
your terminal emulation software.
